Why that fungus smell blowing out from aircon vents lasts only 1 minute and it's gone?
Recently the mildew becomes musty smell - lasting only 1 minute and is gone.
If filters were the culprit, the stink shouldn't last only 1 minute.
Any ideas?

As the air dries the mildew it stops smelling. Then the car sits and the mildew starts smelling up the vents again. It's not a filter problem, it's a mildew problem. The mildew doesn't smell a lot, it just accumulates over time in the vents and is blown into the cabin upon start up.

You may want to attempt to disinfect the evaporator. That's where the water is, and thus the bugs. I would think that you could spray an aqueous solution into the hole for the evaporator temperature sending unit and let it sit.

You have asked this before and I answered you. Do you not read the replies to your threads? I told you practically the same thing that Figuero just did about 3 days ago, but somone corrected me by saying that your filters need to be changed. Although that's not a bad idea, I don't think it's the ultimate solution. Your car sat in some garage sitting idle in a humid environment for several months. What is so hard to understand about that and my proposed solution?

If you would take the time to use the search function here, you would save Benzworld.org a lot of bandwidth and the rest of us with your incessant questions. This issue has been discussed time and time again and Figuero and I have told you how to solve your problem.

What are you waiting for, 50 replies saying the same thing before you act on the advice? I used to think there was a language barrier at play with you, but I now think there is a brain barrier.

Musikmann - filters / disinfectant both do not work. I want to see if anybody can share a solution that works.

See what I found off another website...

RE: Smell Coming From a Car Air Conditioner
By KFL (Guest Post)
I have a 2001 Buick Regal that runs great and gets great mileage. Unfortunately, it also has this mildew smell from the A/C. The smell is only present when I start up the A/C and then it goes away. No smell with heater. I assume bacteria. I've replaced the air filter twice, and I sprayed an entire can of Lysol into the intake w/out the air filter in place with car and A/C running. Smell remains. As I pull into the garage in the summer I switch to vent on high and it helps a tiny bit. Lysol doesn't do it.

How come your car's problem is always so difficult to solve? :D
I had the same problem when I bought the car, then I change the filter and charcoal filter and everything is normal, no more bad odor, you may also go to shamshuipo those car accessary shops and ask, they sell some Japanese products which would (probably) help your problem too.

By the way, the purge valve (MOT) give a tark tark sound when it is on, it is normal too, but you can clean it too, it is in the sticky again.
The fuel pump is next to the fuel filter under the car.

Zaxler, if you sprayed disinfectant into your climate comtrol ducts and that did not help you did not spray it deep enough or in the proper place. Search the posts and I think ohlord tells you exactly how to do it.

Have you actually tried disinfecting or are you just searching for other opinions on various forums? If you are smelling mildew, then killing the mildew will stop the smell.

If he tried and performed

the elimination of the source of the problem,mold and bacteria growing in the a/c system,most likely he did it improperly.You guys keep telling him how and he insists someone must know a solution.Find my diy,it is someplace buried around abouts or visit my web site
www.proudtosaymadeintheusa.com
for enzyme powder guarnteed to deskunk the a/c duct work,along with american made tools applicable to Mercedes repairs.Sub 5 micron oil additive that will not harm your engine and will reduce wear and add several mpg.Dipsticks.17mm special spark boot tool Knuckle saving boot removal tool,carbon fiber trans consoles and shifters,etc.

I believe in removing the mildew. But spraying liquid into a hole that you never see and to make it more wet inside is not good logic; it might temporarily cover up the smell but it will not eliminate the mildew. I know we must spray directly at where the mildew buildup is, so if you guys know how to do this, let me know. I am thinking of using an extension tube. But this leads me to think of an analogy: my son had thick wax inside his ear that really impairs his listening at class; my wife bought an aerosol product at dispensary and sprayed into his ear; problem getting worse. I brought him to a specialist who used an instrument to scrape the wax off and take the wad out, which is so badly soaked and still glistening when shown to me.
In the case of my car, I believe spray is a stopgap which I have to keep doing every few months. This is not what I want.

I also removed the filters, but found them all clean and neat. I have absolute confidence in how this car was used by the previous owner as otherwise I would not have bought it. If filter is the source - the smell won't disappear in just 1 minute. So there is no logic in replacing the filters.

I thank you for all your replies. All are nice guys who want to help. I believe in science and logic. I am still searching other forums and websites. Some of them are pap talkers though. I also talked with an automobile aircon specialist today. On the basis of all these different opinions, some though in conflicts with others, I will work out my own methodology to have this problem fixed.
I understand some of you is losing patience, and I wish to thank them once again.

If your son would have had mildew in his ear instead of wax, a mildewcide spray would have probably worked.:D

Seriously, it sounds like you should just skip the easy, tried and true, advice and simply disassemble the complete HVAC system and soak the entire thing in a 50:50 bleach solution for 24 hours. That will work too.

Figuero - where did you squirt / spray....aircon vents? holes behind the screen wiper? or area behind the filters? How do you make the spray deep enough? What brand of disinfectant? You had the engine running while spraying? For how long do you spray? I want to find out why some people reported this spray method doesn't work at all....or what has gone wrong.

my powder when

mixed and applied as directed will kill off any pathogens,swine flu,skink,mildew,bacteria,ebola:eek:
I don't understand why you need to reinvent the wheel,but go ahead and over analyze everything like you are this problem and you will never get your transmission fluid changed. :rolleyes:

Yes my web site is real, having problems with the server.Some people getin the door and read my news letter and see other pages and some people get a file error or something to that affect.

Hey Ohlord - people defended the spray method and accused something not done properly therefore I want to find out the details and talk apples-to-apples. Too many people just easy talk, without providing details, that's where the disconnect.

How do I eventually resolve this smell issue?
I put the blower on high fan speed, turned on the heater, drove at 140 km/per hr for 20 minutes, with windows down. The next day I put on the aircon, the smell is much weakened.
The following week, I did this again, this time without the heater, and I find there is a slight further improvement, i.e. the smell is still there but much lighter, and lasting only 5 seconds and is gone.

What I found off another website is true...

Zaxler:

Keep doing what you are doing and it will keep (slowly) improving. Once the smell is gone, then develop a habit of turning off the AC and run the blower before you park the car for the day. The source of the problem is moisture accumulation on the evaporator so you need to go to the source, i.e., blow it dry (using the in car blower) before parking the car for the day.

The chemical methods are kind of temporary because the moisture therefore the bacteria will re-accumulate, if the car is parked with a moist evaporator.

And that is why there is "Hong Kong Feet" but not "Dubai feet". :surrender:

Here are a couple posts

It is like Chinese traditional medicine (slow but cure the root cause) vs. western surgery (cut it open and cut out the symptom). :D

ILJ, what is your thought on the above?:cool: You probably have studied/practiced both.

Exactly. I always turned off the aircon 5 minutes before I reached my destination with my old Acura 3.5RL which I bought brand new and owned for 11 years and has never had any smell on the car.

Yes Chinese herbs/medicine like tiger penis or deer horn is much more sustainable than Viagra. :thumbsup::thumbsup:
